In practice, I haven't had any issues with it. :-)
I have setup wifi in a school with currently around 15 access points and
there is no problem roaming around.  They are all consumer routers
reflashed with openwrt.  They used to be all TP-Link, but now I'm
starting to switch to Ubiquiti.  The whole school has both 2.4 and 5GHz
available on the same SSID and different SSIDs for different groups.

Openwrt is a step up from most consumer router software.  Hardware 
reliability (particularly the power dongles) could be an issue, but with
cheap hardware you can afford to have a couple spares ready to go.
If the units use power dongles it might be worth investing in higher
quality power supplies so you don't end up with spares that don't
have power supplies.
